Apparently, an advertising agency hired by Samsung is trying to buy people to post questions about the company on StackOverflow. This is what Delyan Kratunov was asked to do (he declined):

All we need you to do is talk about the SSAC (Samsung Smart App Challenge) and get the word out. How? We were thinking about 4 questions on Stackoverflow over the span of a month..... as well as replies to posts made by other members. Don't worry about finding the questions to reply to because we will send you links.

One would think this agency would have looked into the relevant forum policies, as well as the kind of users that hang out there, before trying to buy them off this way. Now they're facing embarrassment and are having to officially redact their communications. If I were Samsung's chief of marketing, I'd be looking for a replacement agency asap as this puts Samsung in a bad light as well as this ad company.
